ALPHYS FORNICATES WITH THE AMALGAMATES
Once upon an evening, in the cold, dark, miserable underground world of monsters, poor little Alphys was all holed up in her lab like a total loser, contemplating suicide in the process.
"Sigh...why do I even bother feeding myself?" Alphys shrugged with a slight hint of bags under her eyes, sitting at her cluttered computer desk in her Lab and eating a bowl of instant noodles as she watched the uneventful time pass by outside in Hotland, Snowdin and Waterfall through the security camera network hooked up to her computer.
"Is it because of my inescapable, passionate love for Undyne?" she wondered, gulping down the heavily-seasoned, MSG-loaded broth from her noodles and tossing them on the floor beside her in frustration as she leaped out of her chair and began pacing around the room.
"Or is it because I want to see how long I can last like this before I start turning into a sick, creepy psychopath like Asriel did when I turned him into that evil flower abomination?" she sighed, sticking out her long reptilian tongue and eating one of the many flies buzzing around the countless stacks of instant noodle bowls scattered across her entire desk.
"Either way, I've been alone for quite some time now." Alphys sighed, shaking her head with regret and confusion. "According to Sans, I suppose the timeline of this world was...reset...or something like that?" she muttered to herself as she paced back and forth in dismay.
"Well, in any case, my dear, beloved fish waifu hasn't been coming over to see me at all lately, and I'm already REALLY sick of using my body pillow of Undyne as a substitute for the real thing." Alphys sighed, leaning forward and drooping her arms downward with a profoundly ashamed look on her face as she readjusted her glasses awkwardly.
"Well, I guess that means there's only one viable thing left to do, seeing as how Undyne'll kill me if she catches me spying on her morning shower!" Alphys giggled creepily, breaking out into a sinister grin and rubbing her hands together delightedly.
"Oh, but I've got a MUCH more interesting idea than THAT! Yes we do, Alphys, yes we do..." Alphys whispered to herself as she walked over to her storage closet, fumbled through the boxes within, and pulled out some shitty weeaboo catgirl costume materials that she had scraped together from the garbage dump in Waterfall.
"Alright, so this goes HERE..." Alphys whispered to herself, taking her lab coat off for her daily Mew Mew Kissy Cutie weeaboo dress-up routine and putting on her fluffy pink cat ears.
"And this goes HERE..." Alphys giggled and blushed as she put on her beady little cat nose.
"And this goes HERE..." Alphys snickered as she put an adorably pink pom-pom on the end of her tail and wagged it euphorically in a fit of pure joy, causing her plump, rosy ass cheeks to jiggle.
"Oh, and how could I possibly forget THESE?" Alphys laughed and progressively began to sigh as she slipped her adorable little three-toed feet into a scandalously long pair of white-and-pink striped socks, wiggling her delightfully plump little toes while doing so.
"And of course, last but not least, we have the sweet, sugary icing on this fucked-up eldritch bestiality cake that I've already began frying within my totally clean and innocent little mind!" Alphys laughed and sobbed as she put on her extremely skimpy bra and tightened it to absolute perfection so that you could literally see the outlines of her nipples through it.
"Ahh...you can NEVER have enough drugs for something like this!" Alphys sighed with relief, grabbing her roughly purse-sized dog food bag (which was actually full of Dog Residue) and slamming the closet door as her already intense feeling of self-disappointment intensified.
"Alright, now I'm ready!" Alphys declared sassily, putting her lab coat back on and approaching the bathroom, which as you probably already know was actually an elevator that led into her creepy old basement...or as the humans would later call it, her True Laboratory.
As Alphys went down the elevator, she suddenly had this painful feeling in her stomach, that type of feeling that you get when you KNOW that you're getting yourself into some deep shit.
"HURK...oh man, just THINKING about what I'm about to do here is t-triggering m-m-my g-g-gag r-reflex!" Alphys stammered nauseatedly, stumbling dizzily through the grimy, dark, mazelike hallways of her obligatory underground secret laboratory and covering her mouth with her hand as her face began to adopt a rather greenish hue.
"D-don't w-worry, Alphys, j-just t-take s-some d-d-drugs and it'll all be f-f-f-fine and d-d-d-dandy! TEE HEE HEE!" Alphys stammered nervously as she finally reached the main generator room, where her horrifying Amalgamates had been patiently waiting for her.
These melty, goopy, slimy, semi-liquid, white eldritch-abomination spawn-of-Cthulhu "pets" that I speak of were certainly rather difficult to describe, to put it lightly.
For starters, we had Snowy, which was basically Snowdrake's mother (only with her crest having mutated into a living stick-figure body) with the hungry mouths of two equally creepy-looking Vegetoids replacing her eyes; just to top it off, half of her entire body was literally threatening to melt itself right off of the other side. Also, it had an extendable penis-tongue growing in between its legs, just in case you weren't already scared yet.
And then there was Endogeny, which was...a rather intimidatingly massive white dog with who-knows-how-many slimy, freakishly long tentacle-legs as well as an enormous, gaping, slime-oozing hole where its face should have been. Also, its entire body secretly functioned as its dick, with its legs basically serving as additional dicks to power the main one.
And then, of course, there was also Lemon Bread, which was...well, if its name was any indication, Lemon Bread was the slug-like body of Shyren's sister, only with an unnervingly gigantic mouth possessing slimy, black, moldy teeth, as well as piercing angry eyes that looked more than suspiciously similar to the end part of Aaron's tail. Also, it had a huge, slimy penis.
Not to mention Memoryhead, which was...well, judging by its appearance, it was pretty much just a bunch of human skulls melted together, with freaking tentacles concealed within its numerous eye sockets for good measure. No one really knew exactly how this bizarre, unknown thing formed or why, but what Alphys did know was that it was incredibly hideous.
And of course, how could we forget Reaper Bird, who appeared to be an Astigmatism's sideways head floating on top of a terrifyingly long detachable neck, with deformed pieces of Final Froggits for wings, as well what seemed to be an unusually long and stretched-out pair of Whimsalot legs. Also, it had a literal vagina in its eyesocket, just in case you were wondering.
"Got any aces, my dear?" Lemon Bread asked Endogeny, holding his cards with one slimy, pulsating arm and breaking out into a thickly congested yawn with the other as the pus-oozing, gelatinous, moldy black teeth of his enormous face shook with tired anticipation.
In response, Endogeny drooled a whole bunch of moldy black slime from his unwashed, gaping maw and formed said slime into the shape of the word NO as he used his seemingly infinite number of tentacle-legs to hold his cards.
"Hey, quit lying, asshole!" Reaper Bird scolded Endogeny, peeking over at Endogeny's cards with his long, detachable, extendable, spineless neck and nibbling Endogeny's ears with his eye-beak.
Endogeny simultaneously growled and whimpered, bowing his head down and shamefully admitting his ignominious defeat in the art of Go Fish.
"Oh, cheer up, at least you didn't get Snowdrake's mother as your old lady!" Memoryhead laughed, pointing his many lopsided eyes over at the subject...thing...that it was referring to.
"For...God's...sake...shut...up...about...me..." Snowy moaned, her eye-mouths rapidly opening and shutting themselves as half of her entire body melted all over her cards and then reformed itself in an endless cycle, making it excruciatingly difficult for her to see what she was holding.
"So...are you ready for THE THING yet?" Lemon Bread asked Alphys eagerly, raising his eyelids flamboyantly and caressing his animalistic, unwashed penis with his dripping, muscular arm.
"Uhh...ehehehe...c-can I at l-l-least m-make a p-phone c-call f-f-first...?" Alphys chuckled nervously, pulling her phone out from the pocket of her lab coat and dialing Undyne's number.
"Um...hello? A-are you t-there?" Alphys asked Undyne, taking several handfuls of Dog Residue from her bag and snorting them right up her nostrils like a pig. "I'm, uh...I-I-I'm d-down here in the basement having some good clean FUN!"
"Um, hey there, cutie-pie...hey, WAIT a minute, what was that noise? Alphys, have...have you been snorting crack up your nose again or some shit?" Undyne asked her suspiciously.
"Uh...uh uh uh heheh heh YES I MEAN GODDAMNIT NO!" Alphys stuttered abnormally, her glasses beginning to turn hot pink from the influence of the Dog Residue. "I was just, uh...w-won-w-w-wondering what you were planning to do tonight, if you don't mind me asking!"
"Well...whatever the hell you're doing, can you please be quiet down there? Me and Papyrus are coming over to your house for dinner, and we would like to enjoy ourselves in peace for once without you babbling on and on about...ugh...what was that cloying-as-fuck neko anime show called again?" Undyne asked Alphys reluctantly, passing the phone over to Papyrus.
"It's...uh...Mew Mew Furry Cunt!" Alphys laughed awkwardly.
"My, my, what kind of utterly degrading drivel do you WATCH, Alphie? Why, it's no wonder you have such a nasty mind!" Papyrus unintentionally kinkshamed her, causing her to blush quite a bit more than she was comfortable with due to what she was getting herself into.
"Uh...heh...heh...I-I'm not t-too s-s-sick..." Alphys stammered, sweating a little as Memoryhead stared at her. "Uh...h-hey, w-would you l-l-like s-some c-c-c-CRACK?!" she asked him spastically, cowering against the wall in primal fear.
"WHERE?!" Papyrus demanded to know. "I DEMAND TO KNOW WHO IS RESPONSIBLE FOR BRINGING YOU SUCH COPIOUSLY LARGE SERVINGS OF COCAINE!"
"GIVE me that!" Undyne sighed, snatching the phone back from Papyrus. "Hey, Papyrus, got anything else to tell her?"
"Alphys, you be a good boy now, you hear?" Papyrus encouraged Alphys.
"I'm a BOY?!" Alphys gasped in shock.
"Of course not, you're a fucking hermaphrodite!" Reaper Bird groaned sarcastically.
"Reaper Bird, I know what you just said was intended as sarcasm, but I'll have you know that I actually AM, in fact, literally a freaking hermaphrodite!" Alphys informed Reaper Bird sassily.
"Oh, that's just going to make this even BETTER!" Memoryhead panted and moaned, drooling at the eyes and wishing he had a dick so that he could stroke it with his eyesocket-tentacles.
"Alphys, who the hell is this Reaper Bird person you just mentioned? Are you joining some kind of mysterious underground cult or some shit?" Undyne asked.
"W-w-w-well, uh...I g-guess y-you c-c-could...c-c-could...c-c-c-"
"For fuck's sake, SPIT IT OUT ALREADY!" Undyne yelled at her.
"I guess you could s-say that...h-hell is a rather d-d-d-delightful p-p-place i-indeed...uh, a-anyway, G-GOTTA GO, B-B-BYE!" Alphys hastily concluded, hanging up before Undyne could even say anything back.
"Hello? Alphys? ALPHYS? ALLLLPHYYYYS?" Undyne desperately beckoned into the phone.
"DAMNIT, she hung up! Well, seeing as how whatever the hell she's doing right now is apparently her private business, I suppose I can let her handle it herself...even though it's pretty fucking creepy!" Undyne sighed, putting her phone back in her pants pocket.
"Oh, don't worry about it! Why, a cuddly little sweetie-pie like herself wouldn't even hurt a FLY! In fact, she would probably attempt to FORNICATE with said fly if it was big, handsome and muscular like ME!" Papyrus chuckled, wrapping an arm around Undyne and hugging her.
"Papyrus...you're not hiding something from me, are you?" Undyne asked him suspiciously.
"O-of COURSE not!" Papyrus blushed, his eyes darting wildly from side to side as him and Undyne walked out the front door of his house in Snowdin and headed over to the riverperson's fast travel boat, looking for a quick ride to Alphys' not-so-humble abode in Hotland.
"Sigh...I'll bet Papyrus is all but literally skipping along the Yellow Brick Road with Undyne right about now...the poor, sweet, naive, innocent bastard. But me? Well...here I am, everybody. Here WE are, more like it. YEAH! YEAH! HERE WE ARE! HERE WE FUCKING ARE! HERE WE...HERE WE...HERE WE...oh, fuck it, I'm already entirely hopeless anyway." Alphys sighed, shrugging her shoulders and looking down dejectedly at her embarrasingly anime-themed clothing.
"I...know...that...feeling..." Snowy moaned as the Vegetoids that had replaced her eyes perpetually laughed at her endless, immensely agonizing pain.
"So, when do we get to fuck?" Memoryhead asked, extending a multitude of wriggling, fleshy, moist tentacles through his eyesockets and ogling her body with his grippingly girthy gaze.
"Memoryhead, calm the fuck down." Lemon Bread groaned, rolling his eyes and hardening his teeth. "Let's all give her a nice few seconds to prepare herself for the fury of the storm first."
"FUCK THAT, COLUMBO! MATE TO MATE!" Reaper Bird laughed as the madness began.
"Oh, YES...sweet, SWEET revenge..." Memoryhead panted and moaned, foaming at the eyes as her tentacles began to slowly but surely slither their way out through his eyesockets like snakes.
"Please...please kill me..." Alphys whispered hopelessly to herself as the undyingly pissed-off victims of her own experiments surrounded her, all five of their sick, nasty heads overflowing with insanely perverted, horrifyingly degenerate, deplorably fetishistic sexual urges.
"If...if I d-don't m-m-make it t-through t-t-this alive, t-t-tell my g-g-girlfriend that I l-love h-h-her." Alphys told her loyal pets as she swallowed her pride, removed her socks, unbuttoned her lab coat, and even popped her bra right off...right in front of their drooling, sweaty, horny eyes.
"My, my, would you just LOOK at those succulent, juicy chest balloons?" Memoryhead moaned, whipping out his tentacles and tightly wrapping up Alphys' arms and legs in them so that the former pointed straight up and the latter straight down as Snowy began to approach her.
"I'd say it's about time we made you SQUEAL, piggy!" Reaper Bird laughed.
"HA! Good one!" Lemon Bread agreed, giving Reaper Bird a high five.
"Come...to...mama..." Snowy gasped, shambling closer...and closer...and closer...and closer.
"Oh God, no. Oh dear God, NO! NO! NO NO NO NO NO NO NO NO NO-"
"Shh." Lemon Bread shushed her. "Don't worry, darling, this isn't going to hurt a bit."
"It's...it's not?" Alphys sighed with relief as Snowy, the ugliest and perhaps creepiest of the Amalgamates, stared her right in the face with a look of rather confused dread and arousal.
"Of course not! IT'S GOING TO HURT A FUCKING LOT, YOU CRAZY SON OF A BITCH!" Reaper Bird laughed, gluing Alphys' mouth shut using the oily, sticky secretions from its wing.
"I just can't...hold back...the temptation...any longer...I'm sorry..." Snowy moaned, using her disturbingly large eye-mouths to chomp Alphys' delicious, milky boobs clean off.
"MMMMMMMFFFFHHHHHHHH!" Alphys shrieked at the top of her lungs in pain as a copiously large amount of dust sprayed from her womanly chest. Luckily, her voice was muffled by the glue; otherwise, Papyrus and Undyne would have heard her.
"Oh...so...yummy..." Snowy moaned as she chewed up her dairy-rich meal and swallowed it while her tongue-penis licked up the dust that was now leaking from Alphys' breast-stumps.
"THAT was for injecting that stupid fucking DETERMINATION shit into our bodies! And THIS is for melting us together into these fucking revolting spawn of Cthulhu!" Reaper Bird snarled angrily, craning his neck straight down into Alphys' pelvic region and biting her balls clean off.
"AUUUUUUGGGGGHHHHHHH!" Alphys screamed and cried in unbearable agony, her voice somehow still muffled by the sheer thickness of the glue as the dust from her nutsack poured into Reaper Bird's eagerly awaiting, wide-open vagina-mouth.
"Ah, sunny-side up, JUST the way I like 'em!" Reaper Bird snickered, chewing Alphys' testicles into ground-up little bits with his razor-sharp vagina dentata and washing them down with his
glorious, crimson menstrual fluid in memory of a simpler time when he was actually able to cook real eggs.
"Oh, so we're making you WRIGGLE and SQUIRM, eh? Heh heh heh...just like the sickening little LEECH you are, am I right?" Memoryhead laughed, briefly squeezing her entire body with his tentacles and soaking her with what Alphys liked to call "biological lubricant" as her tits and balls suddenly regenerated themselves through sheer determination exposure.
"Wow, looks like a little bit of US is rubbing off on YOU, isn't it?" Lemon Bread chuckled, shoving Alphys into his mouth, chewing on her like bubble gum, ejaculating all over her through the tips of his teeth, then spitting her out like the massive pile of worthless anime trash she was.
"Ugh...you taste like fucking soggy, maggot-infested dog shit! THAT'S MY FETISH!" Lemon Bread spat, wiping his mouth off with his arms and grinning like a sexually aroused crocodile.
"HELP...ME...PLEASE..." Alphys begged God from within her tormented mind, the glue in her mouth wearing off as Endogeny's tongue thoroughly cleansed every last bit of beautiful, dripping cum from her hot, scaly, sweaty body like melted juice off of a popsicle.
"TEE HEE HEE HEE HEE! Oh, that tickles SO much! You naughty, NASTY little boy, you!" Alphys bursted into tears of laughter as Endogeny's long, moist, glistening tongue playfully licked the cum off of her dainty little feet, coating them with a fresh, gleaming layer of saliva as her sweet, sexy toes wiggled in discomfort.
"And now for the grand finale of the first act!" Memoryhead announced dramatically, wrapping Alphys' arms and legs back up with his tentacles in the exact same way as before as Endogeny began to generate Stage III Happiness Froth from his mouth.
"THIS, my friend, is for locking us up down HERE in this fucking SHITHOLE!" Reaper Bird and Lemon Bread yelled valiantly in unison as they both ganged up on Alphys.
"ENDOGENY, I CHOOSE YOU!" Reaper Bird commanded Endogeny, who immediately growled in agreement, taking his position at Alphys' pelvic region and saying AHH.
"SNOWDRAKE'S MOTHER, I FUCKING CHOOSE YOU!" Lemon Bread commanded Snowy, who reluctantly moaned in disagreement, taking her position directly behind Alphys and licking her crotch with her slowly hardening, intensely salivating dick-tongue as Alphys began praying to God for her own survival.
"I...I DON'T WANNA DO THIS ANYMORE, I JUST WANNA GO HOME! HELP ME! HELP ME, MOMMY! DADDY! SOMEBODY...WOULD SOMEBODY PLEASE JUST EUTHANIZE ME?!" Alphys cried.
"Well, I can't say you wouldn't fucking deserve it, PAL! Now let's see what that big ol' MOUTH of Endogeny's was REALLY freaking MADE for, SHALL we?" Memoryhead snickered as Endogeny wrapped his drooling, adjustable-sized, circular mouth around Alphys' fleshy, throbbing penis and began sucking it like his precious, long-lost, ever-so-delicious bone.
"Oh...OHH...so THIS is what a REAL blowjob feels like..." Alphys moaned with pleasure, her dick stiffening even further as Snowy's penis wriggled its way into her tight, juicy, wrinkly ass.
"Please...kill...me..." Snowy moaned in exhaustion as the Vegetoids on her eyes excitedly smiled from ear to ear in disagreement, screaming with second-hand pleasure as Snowy pushed her way deeper and deeper in with each passing second.
"Oh, dear God, this is so...OHHHH...so WRONG and yet so...OHHHHHHHH...SO RIGGGHT!" Alphys moaned in ecstasy as her entire body quaked from sheer arousal, causing at least two pints of piping-hot sploodge to shoot right out of her big fat dick into Endogeny's loving mouth.
"So...much...utter depravity..." Snowy moaned as her Vegetoid mouths licked up the goopy, melty, determination-loaded cum that was now leaking from Alphys' poor, poor butthole.
"I...I'm so SORRY! For...for EVERYTHING! I...I give up! Just PLEASE don't kill me, I beg of you! PLEASE spare me, PLE-HE-HE-HEASE!" Alphys sobbed, tears streaming down her face as Memoryhead untied her and set her down on the grimy, filthy, cum-stained floor.
"No...no, you're NOT sorry. If you were sorry, you would have let us out of here a long fucking time ago, you crazy bitch." Lemon Bread growled at her, pulling out his frightfully massive, smegma-coated erection and rubbing it in between his juicy lemon breasts for lubrication.
"Aw, what are YOU fucking complaining about? You should feel LUCKY to be getting a nice, warm, long-legged footjob from yours truly, DADDY LONGLEGS!" Reaper Bird laughed, extending out his long, spindly legs and curling his lovely, eagle-like toes around Alphys' still-dripping cock.
"C'mere, little buddy, how about a nice big FUCK?" Lemon Bread laughed as he wrapped his arms around Alphys in a mockingly affectionate manner and promptly began forcefully ramming his veiny, pulsating, throbbing, meaty dick into Alphys' glory hole.
"Ugh...I KNEW I should have used...UGGGH...condoms for this...hey, wait a minute, shouldn't my...URRRK...cum supply already be...AGGGH...exhausted from that last...OHHHH...outburst?!" Alphys suddenly realized as dust started to leak from the tattered, torn walls of her vagina.
"You poor, naive bastard...in THIS world, it's rape or BE raped! If you didn't WANT us to do this to you, then you shouldn't have even fucking come down here in the FIRST place!" Reaper Bird laughed hysterically as his nice, long and flexible little bird toes slid firmly up and down Alphys' doughy, wrinkly shaft, feeling the dust rush into her soft, spongy penile tissue as he spoke.
"What have I done...WHAT HAVE I DONE?!" Alphys moaned as both her vagina and her dick throbbed with excitement, clearly ready to burst. Both Reaper Bird and Lemon Bread could clearly feel that Alphys was deliciously eager to let out her inner feelings about them.
"THREE, TWO, ONE, NOW!" Lemon Bread commanded Reaper Bird, who then stretched out his neck and chomped Alphys' entire dick (minus the balls) right off at the exact moment of climax.
"WAUUUGGGGHHHHHH!" Alphys wailed in pain as generous helpings of dusty, musty cum gushed out from both her ravaged, lemon-juice-soaked vagina and the remaining stump of her penis; her scream was so loud that Undyne and Papyrus heard it from all the way over at their dinner table, causing them to spit out their spaghetti (which already tasted like shit by the way).
"Just what in the actual name of FUCK is going on down there?! Here, Papyrus, grab my hand! We really need to go and see what my crazy-ass lunatic of a girlfriend is up to!" Undyne growled, abandoning her spaghetti and tugging Papyrus along behind her into the elevator.
"Ooo, somebody's coming! I can already SENSE it! You'd better run and hide, you kinky son of a bitch! Also, hide the evidence while you're at it!" Memoryhead chuckled, unwrapping his tentacles from Alphys' body and retracting them back into his eyesockets.
"NO...WAIT! There is still one last thing that I absolutely MUST do before I leave! This entire experiment DEPENDS on it!" Alphys demanded as she grabbed a huge pile of emergency wipes from the room's supply closet and wiped the remaining dust off of her body with them.
"And THAT would be exactly WHAT, may I ask?" Lemon Bread asked her curiously, cocking an eyebrow in surprise. "Oh, for fuck's sake, don't tell me you're SERIOUSLY about to-"
"Oh, YES! I'm going to kinkily fuck my own DOG while wearing an anime CATGIRL costume! Why? Because if there's one thing you guys have taught me, it's the fact that I have absolutely NO shame or standards." Alphys smirked, shooting a seductive winking glare toward Endogeny.
"Alright, doggy, show me what makes your COCK tick!" Alphys walked sexily forward and sassily commanded Endogeny, who then responded by holding out his long, dripping tentacle-legs in front of Alphys' face seductively.
"Oh...oh, my...you want me to stroke your LEGS? H-how kinky! Eheheheh..." Alphys blushed, reaching into her dog food bag and snorting a few more handfuls of Dog Residue up her nose as she crawled underneath Endogeny and laid herself out face-up on the floor in preparation.
"Oh...oh God, I can't even LOOK! It's...it's just too disgusting!" Lemon Bread retched, with all of the other Amalgamates cringing disgustedly in agreement as the fetishistic rampage began.
"Don't worry, Mother's here for you, sweetheart! Let Mother show you some loving AFFECTION, dearie!" Alphys laughed sociopathically as she literally gave Endogeny footjobs, handjobs, blowjobs, boob jobs, pussy jobs and even butt jobs...all at the same time.
"I...I think I'm gonna hurl." Memoryhead shivered, gagging up several eyeballs into its mouth.
"Oh yeah, Mother's gonna take REAL good care of YOU, Mr. Puppikins! Why, I dare say Mother's even got a nice big BONER for you, and no less but the GOOD kind, of course!" Alphys moaned with excitement, briefly unplugging her mouth to speak as she continued stroking Endogeny's massive, gorgeous legs with literally every possible part of her body.
"AWOOOOOOOoOooooOoooO!" Endogeny howled with pleasure, its mouth opening and closing itself rapidly and involuntarily as its drooling became progressively more intense and its vibrations became progressively more vibratory.
"Would somebody please just climb up here with a ladder and a knife and just gouge my fucking eye out? I think I'd much rather be blind right about now." Reaper Bird sighed.
"Oh, you're such an adorably NASTY little shit! Who's a sick perverted fuck? Yes, you are, Mr. Puppy, oh yes you ARE!" Alphys teased Endogeny, stroking his legs faster and faster and even faster yet as the moment of contention rapidly approached.
"I'm...so...JEALOUS..." Snowy moaned delightedly as her Vegetoid eyes frowned in...revulsion?
"Come on, sweetie, show me your SPUNK! Oh...OHH...OHHHHHHHH, YESSSSSSSS! My, my, you're making such a hot, sticky MESS! AHH...SWEET SAUCE...ALL OVER MY BODY..." Alphys moaned as Endogeny literally drooled out five gallons of semen all over her entire naked body.
"Oh, dear God, WHY DO I HAVE SUCH A HUGE FUCKING BONER RIGHT NOW?!" all five of the Amalgamates reflexively thought to themselves upon witnessing the utterly repugnant sight.
"You know the rules, sweethearts! You make a big goopy mess, YOU FUCKING CLEAN IT UP!" Alphys screamed psychotically, struggling to speak through the disgustingly thick layer of sperm covering her face as all five Amalgamates licked their lips and dug right in.
"Come on, guys, show me what you're MADE of!" Alphys laughed as all five Amalgamates proceeded to lick every last drop of cum off of her sweaty, naked body in a combined effort, even going as far as to literally dip her entire body into the massive pond of cum surrounding her and roll her around in it like a pathetic, miniscule little fry being dipped in ketchup.
"OHH, MOMMA, THAT FEELS SO GOOD!" Alphys moaned as Snowy used her Vegetoid mouths to suck her luscious, bloated tits until the creamy, delicious milk fervently spewed from them, prompting Snowy's babies to then lovingly kiss them with delight as Alphys blushed in humiliation.
"OH, I FEEL LIKE I'M IN MY MOTHER'S BLESSED WOMB AGAIN..." Alphys moaned as Reaper Bird shoved her headfirst into his vagina and painfully chewed her with his razor-sharp teeth as his vaginal digestive juices splashed all over her, soaking her in pure, unadulterated liquid filth.
"Let us never...speak of this...again..." Alphys coughed and wheezed as Reaper Bird finally spat her out onto the floor, wiping his mouth with his wing and nearly vomiting all over her in shame.
"Mmmmmm...that was FINGER-LICKING good!" Lemon Bread laughed uproariously, patting his belly and uttering a resounding burp as Alphys put her lab coat back on and grabbed her bag.
"I'm going to be having nightmares about this shit for months on end and I feel perfectly fine!" Memoryhead shuddered sarcastically, trying desperately not to also puke all over the floor in disgust.
"Man, isn't this game's fanbase just nothing short of GREAT?!" Reaper Bird laughed maniacally, licking the last few drops of tasty dog sperm off of his wings.
"I...hate...myself...so much..." Snowy moaned, beginning to melt even more severely from the sheer amount of seminal fluid (and breast milk) she had just consumed.
"W-well...uh...eh...heh...ehehe...that was, uhh...pretty fun, guys! I'm just going to go and CRUCIFY myself now, if you don't mind! I'm sure it'll be good riddance anyway! TEE HEE HEE!" Alphys giggled, turning around to see Undyne and Papyrus staring directly at her while Endogeny slyly drooled out the last remaining bit of his orgasm fluids all over her face and clothes.
As you can probably imagine, Undyne and Papyrus were both utterly speechless; their jaws had been thoroughly dropped, and their eyes felt like they were about to melt right out of their sockets.
"Uhh...I c-can explain..." Alphys stammered in shock with a creepily awkward smile, blushing so brightly that it was actually illuminating the entire room like a lightbulb and causing her face to sweat.
"Alphys. What. The fuck. WAS that. And WHY?" Undyne asked Alphys, struggling to maintain her composure after seeing what her beloved girlfriend was really like on the inside.
"Did...did I ever tell you the definition...of insanity?" Alphys asked Undyne, trying not to literally die from embarrassment overload as Endogeny briefly leaned over her head and sucked on it.
"Yes! Why, in fact, it would seem that...judging from what I've just seen anyway...the TRUE meaning of insanity is actually being a dirty, nasty, deplorable little PROSTITUTE like yourself!" Papyrus spat disgustedly, causing Alphys to literally develop a fever from blushing too hard.
"No! Please stop! PLEASE! I'M BEGGING YOU! You're...you're literally KILLING me!" Alphys begged them as she threw her bag onto the floor and covered up her drug-tinted eyes with her hands, her knees quivering like Jell-O as she trembled in fear with piss running down her legs.
"We all fucking deserve it..." the Amalgamates self-consciously muttered under their breath as Alphys curled up into a traumatized little ball on the floor and began sucking her thumb.
"Hey, Alphys, remember that part where you fucked your own DOG? Well, guess what? Believe it or not, I actually FAPPED to that! And I'm only going to be ashamed of myself for the rest of my entire LIFE! That's what friends are for, right?!" Undyne laughed, kinkshaming Alphys even further.
"WAUUUUUGGGGGHHHHH! I...I...I JUST CAN'T TAKE THIS ANYMORE! THIS IS...OH MY GOD, THIS IS JUST TOO MUCH FOR ME! I AM SO DEAD! IF KING ASGORE FINDS OUT WHAT I JUST DID...OH DEAR GOD, I AM SUCH A BIG FAT PILE OF SNIVELING TRASH, I MEAN SERIOUSLY, I AM LITERALLY GARBAGE, I AM ACTUAL GARBAGE! LIKE, SERIOUSLY, JUST FREAKING KILL ME ALREADY!" Alphys cried hysterically, clutching her head and writhing violently on the floor in a fit of panic until she passed out from overexertion.
"Man, what an utterly pathetic LOSER!" Papyrus laughed hysterically, wiping the tears of laughter from his eyes so that no one would see them.
"Aw, come on, Papyrus!" Undyne laughed, giving Papyrus a pat on the back. "Sure, she might be a pathetic piece of fat smelly garbage..."
"But she's a pathetic piece of fat smelly garbage with a big heart?" Papyrus sighed, rolling his eyes and facepalming.
"Hey, wait a minute, how'd you know I'd say that?" Undyne asked him, prompting yet another glorious facepalm from the great and almighty Papyrus.
"Anyway, come on, let's drag her over to my house!" Undyne told Papyrus as the two of them scooped up her thoroughly defiled body and hauled her over to Undyne's house in Waterfall.
The next morning, Alphys woke up on Undyne's couch, fully dressed in her catgirl outfit...except that her socks were missing! Luckily, Papyrus wasn't there to nag her about it.
"Whew...at least I'm still alive, I guess. That's good, I suppose. Now where did I leave my socks?" Alphys wondered as she looked around the living room curiously.
"Hey, wait a minute, there's something REALLY fishy about all of this..." Alphys realized, picking up a rather odd scent and noticing that there was still saliva all over her feet as she walked over into Undyne's bedroom...where Undyne was busy masturbating in her bed with Alphys' socks.
"OH, MAN...these stinky, sweaty socks feel SO good on my cock...OHHHHH- MY GOD! ALPHYS! WHAT IN THE HELL DO YOU WANT? I'M KIND OF BUSY RIGHT NOW!" Undyne screamed as Alphys suddenly kicked the door down.
"Undyne, as my formerly trusted housemaid, you have officially lost your overnight laundry-handling priveleges!" Alphys snidely kinkshamed Undyne, causing her to blush and giggle awkwardly in a very dorky fashion.
"Wow, I guess that deep down on the inside, we're all just like you, aren't we?" Undyne chuckled, scooping Alphys up into her arms and hugging her.
"Oh, don't kid yourself, your fetishes could never even DREAM of being as nasty as MINE! Now go ahead and keep on worshipping these stinky, sweaty feet of mine like there's no tomorrow!" Alphys encouraged Undyne, crossing her legs and wiggling her toes seductively.
ONE CRAZILY LONG SESSION OF RUBBING, LICKING, KISSING AND TOE-SUCKING LATER...
"Alphys, you really are the sickest fuck I think I've ever met." Undyne told Alphys as the two of them laid together on the roof of Undyne's house, gazing at the star-like crystals overhead.
"I know." Alphys giggled as the two of them proceeded to twirl their tongues together and french-kiss each other passionately and infectiously, with saliva dripping off of their tongues.
And then Undyne caught a horrible Amalgamate-related STD from Alphys, causing her to shrivel up and melt and die less than two decades later...because why not?
"Alphys...I...fucking hate to love you...so goddamned much..." Undyne, who was only about 35 years old, coughed and wheezed as she laid on the deathbed of an unassuming local hospital in New York City, where the grass was brown and the girls were ugly.
As a result, both of Undyne's kids shot Alphys a glare that was almost as deadly as Undyne's cancerous fandom-induced disease, which had recently been diagnosed as Alphamalgitis.
"Uhh...I c-can explain..." Alphys laughed nervously, blushing as her now-adopted kids, Alphyne the Lizard and Undys the Fish, saw the not-so-subtle name of Undyne's cancerous disease.
"You, old ma'am, are cruising for a BRUISING!" Alphys' gay-ass sons (who were somehow both male by the way) threatened her, rolling up their sleeves as Alphys backed up against the wall.
"Now, now, there's no need for violence...oh, what the heck? Come on, boys, HIT ME WITH ALL YOU'VE GOT!" Alphys laughed maniacally, pulling a whip out of her pocket and handing it to them...after stripping herself naked in the hospital room, of course.
"You know, I'm not really into women, but this shit is making my fucking SWEAT sweat!" Alphyne drooled as he whipped Alphys right in her marshmallow-ass boobs.
"You can say that again!" Undys drooled, sticking his hand down his pants and masturbating furiously as he watched the rear end of Alphyne's skintight skinny jeans quake with energy.
"Hey, Alphys, why don't you try kissing a GUY for once?" Alphyne chortled, continuing to flog Alphys with the whip as him and Undys pulled their shirts off and french-kissed each other.
"YEAH, Alphys, why don't you try kissing a DUDE for once in your sad weeaboo life?" Undys laughed as Alphyne passed him the whip.
"OH, YEAH, INSULT ME MORE, COME ON, INSULT ME MORRRE!" Alphys moaned as her kids beat the ever-loving shit out of her while calling her various words related to "fat", "weeaboo", "retard", "bitch" and "faggot".
Anyway, long story short; Alphys got thrown in jail, and her kids grew up into a gay porn couple, and they both caught Alphamalgitis, and both of them died. THE END.
